RAID Subsystem : RAID 0+1

RAID 0+1, is a dual-level RAID and achieves a balance between the increased data availability of RAID 1, mirroring, and the increased read performance of RAID 0, striping. Do not to confuse RAID 0+1 with RAID 10, they work differently and RAID 0+1 is what is recommended.


For maximum performance configure the database server shown in the following example:

• Two disk RAID 1 for the operating system and database software

• A small, four disk RAID 0+1, or two disk RAID 1 for database logs

• A larger RAID 0+1 for the main database files

o To reduce cost, swap out the RAID 0+1 for a RAID 5. However,this will result in slower performance.
